Definitions

  • the invention relates to a printing press cylinder washing device for washing at least one cylinder in the printing unit of a printing press.
  • the printing press cylinder washing device is particularly suitable for offset printing presses.
  • washing bar From practice it is known to insert a washing bar from a cylinder end into a washing device and to connect it to a connection unit via which washing liquid, for example water or liquid washing agent or solvent or compressed air, is fed to the washing bar. Furthermore, washing devices are known from DE 30 05 469 C2, DE 28 15 388 C3 and EP 0 334 173 A1, in which the washing bar can be adjusted between a washing position approximating the cylinder to be cleaned and a basic position distant therefrom.
  • washing liquid for example water or liquid washing agent or solvent or compressed air
  • the wash bar must in particular be inserted into the printing unit from one end of the printing unit cylinder when there is no space for the washing device at the top and on the side of the cylinder and the washing bar must be arranged below the lower half of the cylinder. Access to the lower half of the cylinder is often only possible through a relatively small opening in one of the machine side stands.
  • the narrow space conditions not only make it possible to insert the washing bar into the washing device, but also to connect the washing bar to the supply lines for washing liquid and / or compressed air.
  • the compressed air can be used to press a washcloth onto the cylinder to be cleaned and / or to actuate pneumatic drives of the washing device.
  • the soiled washcloth must often be removed from the washbar, for example once a week, and replaced with a clean washcloth. To do this, due to the limited space available, the wash bars must be removed from the printing unit and then used again.
  • the washing device contains a washing bar 6 with a washing cloth 8, which is wound on the washing bar 6 by a clean cloth spindle 10 onto a dirty cloth spindle 11 and has a cloth section 12 opposite the cylinder 2 with a small distance of less than 10 mm.
  • This wash cloth section 12 can be applied to the cylinder surface 15 by a pressure element 14 of the wash bar 6.
  • the pressing element 14 is preferably a hose that can be expanded by compressed air.
  • the washcloth section 12 can be applied directly to the cylinder 2 through the washing bar 6, without the interposition of an expandable pressing element 14.
  • the washing bar 6 is provided with a spray device 17, through which washing liquid, for example water or liquid detergent or solvent, is sprayed onto the rear side of the washing cloth section 12 facing away from the cylinder 2.
  • the washing bar 6 is carried by a suspension device 20, by means of which the washing bar 6 can be displaced between the washing position shown in FIG. 1, approximating the surface of the cylinder 2, and a starting position further away from the cylinder surface.
  • the starting position of the washing bar 6 is shown in broken lines in FIG. 1. In this starting position, the washing bar 6 is located behind an opening 22 of the side frame 3 within the height dimensions of this opening 22.
  • Connection means 28 are provided on the washing bar 6, of which a hose 29 for supplying washing liquid to the spray device 17 and a further hose 30 for supplying compressed air into the pressing element 14 leads to its expansion.
  • the spray device 17 can spray washing liquid onto the cylinder 2 or onto the cylinder 2 and onto the washing cloth 8.
  • the linear guide device 24 consists of a first guide body 32 fastened to the suspension device 20 and of a second guide body 33 provided on the washing bar 6.
  • the two guide bodies 32 and 33 form a plug connection running in the longitudinal direction of the washing bar, which holds the washing bar 6 on the suspension device 20, but the Retracting and extending movement of the washing bar 6 in the longitudinal direction of the washing bar is permitted when the washing bar 6 is in the dot-dash starting position in FIG. 1.
  • connection unit 36 and the connection means 28 of the wash bar 6 are opposite one another in the wash bar longitudinal direction 25 arranged in such a way that the connecting means 28 of the washing bar 6 are moved towards the connecting unit 36 of the hanging device 20 and are automatically coupled to it when the washing bar 6 is moved into the hanging device 20 in the starting position 6 '.
  • other energies for example hydraulic fluid or electric current, can also be transmitted through the connection unit 38 and through the connection means 28 automatically coupled to them.
  • a drive 40 for preferably gradually rotating the dirty cloth spindle 11 is fastened.
  • the drive 40 is connected via a plug-in coupling to the dirty cloth spindle 11, the two coupling parts 41 and 42 of which lie opposite one another in the longitudinal direction 25 of the washing bar and are automatically coupled or uncoupled to one another when the washing bar 6 is plugged onto the suspension device 20 in the longitudinal direction 25 of the washing bar or is subtracted from this.
  • connection means 28 against the connection unit 38 is achieved in a simple manner in that the locking slot 46 has a cam surface 47 directed obliquely to the connection unit 36.
  • spring means 48 are arranged between the wash bar 6 or the second guide body 33 and the arm 34 of the first guide body 32, which counteract the insertion movement of the wash bar 6.
  • the suspension device 20 is mounted on the two printing press side stands 3 and 4 so as to be pivotable by bearings 50 about a pivot axis A which runs parallel to the axis of rotation D of the cylinder 2.
  • two pneumatic cylinders 52 and 53 are provided, the cylinder housings 54 of which are pivotally attached to a machine cross member 55 about a pivot axis B, which runs parallel to the other two axes A and D.
  • the piston rods 56 of the two compressed air cylinders 52 and 53 are connected to the first guide body 32 of the suspension device 20 so as to be pivotable about pivot axes C.
  • the pivot axes C are parallel to that Pivot axis A and the rotational axis D.
  • the two pivot axes C are aligned with one another.
  • the two pivot axes B are also aligned with one another.
  • the two compressed air cylinders 52 and 53 are arranged at a distance from one another in the longitudinal direction of the washing bar.
  • the two compressed air cylinders 52 and 53 can pivot the suspension device 20 with the washing bar 6 fastened thereon on an arcuate movement path around the pivot axis A between the washing position shown in solid lines at the top in FIG. 1 and the starting position shown in dash-dotted lines below.
  • the compressed air cylinders 52 and 53 are preferably reciprocally pressurized units.
  • FIGS. 2 to 6 parts corresponding to FIG. 1 are provided with the same reference numbers.
  • the pivot axis A of the suspension device is replaced by four pivot axes A1, A2, A3 and A4, which together form a parallelogram or trapezoidal joint.
  • the pivot axes A1, A2, A3 and A4 run parallel to one another and parallel to the axis of rotation D of the cylinder 2.
  • the two pivot axes A1 and A2 are formed by bearings on the machine crossmember 55.
  • the pivot axes A3 and A4 are formed by bearings in a bearing block 60 of the suspension device 20, to which the first guide body 32 of the linear guide device 24 is attached.
  • the drive 40 for the dirty cloth spindle 11 is a compressed air cylinder which is pivotally mounted on the first guide body 32, which is carried by the suspension device 20, via a pivot axis F, which runs parallel to the axis of rotation D of the cylinder 2.
  • the piston 66 of the compressed air cylinder 40 is drivingly connected to the dirty cloth spindle 11 via a joint with a pivot axis G and a lever 67 via the coupling 41, 42 of FIG. 1. 3, the clean cloth spindle 10 and the dirty cloth spindle 11 are mounted in side plates 70 and 71 of the washing bar 6, which are fastened on the base plate 62.
  • a cloth end indicator 74 attached to the machine side stand 4 then generates a signal by which the washing device and the printing unit are switched off, when the end of the washcloth is almost reached, but also when the wash bar 6 is not in the washing position shown in FIGS. 1, 2 and 3.
  • the cloth end indicator 74 thus simultaneously fulfills a safety function.
  • FIG. 6 shows the first guide body 32 of the suspension device 20 with the base plate 62 and its guide segments 63 and 64 in the washing position and, denoted by 32 ′, 62 ′ and 64 ′, in its starting position underneath.
  • a second linear guide device 76 adjoins the front end of the linear guide device 24 facing away from the connection unit 36, which extends under a tread plate 78 of the printing unit and subsequently guides the wash bar 6 to the first linear guide means 24 in the longitudinal direction 25 of the wash bar 6.
  • the second linear guide device 76 is configured with respect to the individual guide elements 62, 63, 64 and 65 in the same way as the first linear guide device 24.
  • the second linear guide device 76 is located at the height of the first linear guide device 24 when the latter is in the downwardly pivoted starting position, such as this shows Fig. 6.
  • the washing bar 6 on the side 80 of the tread plate 78 facing away from the cylinder 2 can pass through the machine opening 82 underneath and onto the second linear guide device 76 inserted and guided in the longitudinal direction 25 of the washing bar under the step plate 78 and then transferred to the first linear guide device 24 while it is in its starting position.
  • the washing bar 6 with the washing cloth 8 can be guided from the first linear guide device 24 in its starting position in the longitudinal direction 25 of the washing bar to the second linear guide device 76 and removed therefrom under the tread plate 78, for example in order to replace the washing cloth 8.
  • the second linear guide device 76 stands on the machine floor 84.
  • the wash bar located on the second linear guide device 76 in FIG. 6 is identified there by 6 ′′ and its washcloth by 8 ′′.
